100

these are the products of photosynthesis

what is glucose and oxygen

100

this is the worded equation for respiration

what is glucose + oxygen (gives you) water+carbon dioxide+energy

100

this type of waste will pollute potable water and cause an increase pest population  

what is solid waste

100

this is the ability to do work

what is energy

100

these are 2 metals that will not react with diluted acids

what are silver, copper, platinum

200

with this crop production method, crops are grown in a house made from a transparent material such as glass

what is greenhouse farming

200

two features common to respiratory surfaces in animals and plants

what are have a large surface area, moist, thin 

200

this practice eliminates body odours, allows social acceptance and prevents infections

what is personal hygiene(community hygiene)

200

this is the SI unit and equation for calculating work

what is joules;what is force X distance

200

poor conductors, flexible, brittle, low tensile strength, dull are all properties of

what is non-metals

300

this is the reagent/chemical and positive test for a reducing sugar

what is Benedict's solution and orange-red precipitate

300

three differences between aerobic and anaerobic respiration

what are aerobic requires oxygen; anaerobic does not; aerobic occurs in the mitochondria while anaerobic occurs in the cytoplasm; aerobic produces more energy from the same amt. of substrate than anaerobic

300

this type of organism causes disease in its host

what is a pathogen

300

this is the principle of conservation of energy

what is energy cannot be created or destroyed but can be converted from one type to another

300

resistant to corrosion, lightweight, shiny, good conductor of heat are advantages to using which metal for cooking and canning

what is aluminium

400

these are the 2 parts of the digestive system that aids with mechanical/physical digestion

what are the teeth and the muscles of the alimentary canal

400

this is how lactic acid is formed in muscles and removed

what is from anaerobic respiration(oxygen debt) in animals; it is removed when oxygen becomes available and breaks it down to carbon dioxide and water

400

these are the stages in the life cycle of the housefly and the mosquito

what are the egg, larva, pupa and adult

400

this is the equation for calculating momentum

what is p=m x v

400

Coating, sacrificial protection and electro-plating are all methods used to prevent what?

what is rusting

500

these are the 4 conditions necessary for the growth of micro-organisms

what is moisture/water, oxygen, suitable temperature and suitable pH

500

this pollutant combines more readily with haemoglobin and reduces the oxygen carrying capacity of the lungs

what is carbon monoxide

500

name of the process by which methane is produced from anaerobic breakdown of organic waste such as manure

what is biogas production

500

A block has a weight of 50N and was pushed through a distance of 25N across a floor, determine the work done?

what is 500J

500

aluminum + hydrochloric acid

what is aluminum chloride + hydrogen
